射频消融右侧房室旁束１５例，其中显性旁束１０例，隐匿性旁束５例。后者根据电生理检查进一步确定旁束位置。显性旁束可根据常规心电图的预测主波方向作出旁束的大概定位。采用左前斜位３０°透视，以心腔内心电图及心导管的活动情况定位粗标三尖瓣环的位置，以三尖瓣环为时钟，根据大概定位细标大头电极导管，找到最短的Ａ－Ｖ和Ｖ－Ａ间期或ＡＶ完全融合处进行射频消融。 Radiofrequency ablation of the right atrioventricular bundle in 15 cases, including 10 cases of dominant paranasal, occult paracentesis in 5 cases. The latter based on electrophysiological examination to further determine the next beam position. The dominant side of the beam can be based on the conventional ECG predicted wave direction to make the approximate positioning of the side beam. Using the left anterior oblique 30 ° perspective, the cardiac electrocardiogram and cardiac catheter activity positioning coarse tricuspid annulus position to the tricuspid annulus as the clock, according to the approximate location of the main electrode catheter to find the shortest A -V and V-A interphase or AV complete fusion radiofrequency ablation.
